Fiber PDH Multiplexer 19" Rack 4 Channels 10/100/1000M Ethernet
Switch Interface
Ethernet Switch Interface Advantages
► Ethernet interface rate is 10M/100/1000M, half/full duplex auto-
Negotiation
► 4 Channel Ethernet interface is switch interface, support VLAN,
can set to 4 channel logical isolation
► 2 expansion interface, extend 1~2Channel asynchronous data, such
as RS232/RS485/RS422/Manchester code;
► 1Channel PCM digital business phone (optional)
► The transmission distance is up to 2-120Km without interruption

Fiber PDH Multiplexer Overview
This device provides 1-4Channel E1 interface, master optical fiber
interface and backup optical fiber interface, 1-4Channel
10M/100/1000M Ethernet interface (Line Rate 1000M) and 2 expansion
interface. 4Channel Ethernet interface is switch interface, can
support VLAN. 2 expansion interface can be used as the transmission
channel of RS232/RS485/RS422 asynchronous data, voice signal, 2/4
line E&M audio signal, switch signal, Ethernet signal
(Bandwidth 2M). It is very flexible. It has alarm function. The
work is reliable, stable, and low power consumption, high integration, small size.
